As the first iteration of protocells, monocells are primitive, digital, artificial life forms based on lattice structures. Guided by artificial selection, they evolved rigid, springy, naked skeletons with no membranes or differentiation in material and resemble organic Radiolarians living in Earth’s oceans. Monocells tend to cycle through different configurations in their evolutionary path, some stable, some in perpetual motion. Undiscovered earlier versions of protocells probably had no way of interacting with the graphics pipeline and, if at all, existed as simple graph data structures. Monocells were the first protocells which evolved monochrome display through ordered dithering.
